Abstract
Description
- This invention relates to a protection device, and in particular to a protection device intended for use in protecting against injury or damage caused by explosions, for example in the event that a suspect package or object which is thought may contain an explosive device is located.
- Where suspicious packages, items of luggage or the like are found, it is known to place a blast suppression device, for example in the form of a blast suppression blanket, over the package or the like to contain fragments in the event that an explosive device within the package or the like detonates. Clearly, containment of such fragments reduces the risk of injury to individuals close to the package or the like, and also reduces the risk of damage in the surrounding area.
- A number of blast suppression devices are known. For example,
GB 1459743 US 3648613 both describe blast blankets designed for this purpose, the blankets including a number of layers of a suitable ballistics material to resist tearing or rupturing of the blanket and avoid or reduce the passage of fragments through the material. In the event of detonation, fragments resulting from the explosion are thus contained by the blast suppression device. Consequently, the risk of damage or injury is reduced.DE 19717474 describes a blast suppression device intended for use in mailrooms or the like and into which suspect letters or small packages can be placed so as to contain fragments in the event of explosion. - Although such devices may be successful in reducing the risk of injury or damage in the event of an explosion, it would be preferable to prevent detonation and thereby further reduce the risk of injury or damage.

GB2470123 - Whilst the arrangement of
GB2470123 - According to an aspect of the invention there is provided a protection device comprising a covering incorporating an electromagnetic screening layer, a first antenna, a second antenna, and an inhibitor device operable to cause the first and second antennae to transmit respective inhibiting signals at or over respective frequencies or frequency ranges into a volume enclosed, at least in part, by the covering, in use.
- It will be appreciated that by providing two or more antennae, and arranging for the inhibitor device to transmit inhibiting signals via the antennae at or over different frequencies or frequency ranges, the reception of command signals transmitted over a wider range of frequencies to an item located within the volume defined, in part, by the covering is impeded.
- The first antenna conveniently takes substantially the form of a loop. The loop is preferably suspended at a position spaced inwardly of the screening layer.
- The second antenna conveniently takes the form of a discrete antenna, conveniently located within a housing. The second antenna could take a range of forms, for example comprising a suitable conductor or a conductive track on a PCB. One or more additional antenna may be provided adjacent and associated with the second antenna and connected to the inhibitor device to allow the transmission of inhibitor signals over further frequency ranges.
- The second antenna is conveniently suspended from the cover. Where one or more additional antennae are provided, these are preferably suspended with the second antenna. Preferably, the manner in which the second antenna is suspended allows adjustment of the position of the second antenna. By way of example, it may be carried upon a strap or straps of adjustable length. A hook and loop fastener may be used to adjust the length of the strap or straps.
- It will be appreciated that by supporting the second antenna in this manner, the second antenna may be located very close to the suspect item. As a result, effective inhibition can be achieved without the need for the transmission of an excessively powerful inhibiting signal. The risk of disruption to communications in the vicinity of the protection device is reduced.
- The inhibitor device may incorporate additional variable signal sources such as programmable voltage controlled oscillators operable to generate the inhibitor signals for transmission via the first and second antennae.
- The covering may further incorporate ballistics materials.
- The covering may be supported upon a frame. The frame may be of a flexible or foldable form. Alternatively, the frame may be of an inflatable form.
- According to another aspect of the invention there is provided a protection device comprising a covering incorporating an electromagnetic screening layer, an antenna, and an inhibitor device operable to cause the antennae to transmit an inhibiting signal into a volume enclosed, at least in part, by the covering, in use, wherein the antenna is suspended from the covering. Preferably, the manner in which the antenna is suspended allows adjustment of the position of the antenna. By way of example, it may be carried upon a strap or straps of adjustable length. A hook and loop fastener may be used to adjust the length of the strap or straps.
- The invention will further be described, by way of example, with reference to the accompanying drawings, in which:
-
Figure 1 is a diagrammatic view illustrating a protection device in accordance with an embodiment of the invention. - Referring to
Figure 1 , aprotection device 10 is illustrated. Theprotection device 10, in common with that described inGB2470123 edge regions 12a that rest upon aground surface 14, in use. As shown, in use, thecovering 12 is positioned over asuspect item 16 and defines, with theground surface 14, avolume 18 surrounding theitem 16. - The covering 12 includes an
inner layer 20 in the form of an electromagnetic screening material, and anouter layer 22 in the form of a suitable ballistics material. It will be appreciated that the presence of theinner layer 20 attenuates the transmission of electromagnetic signals into thevolume 18. Accordingly, if theitem 16 includes a radio receiver operating to detonate part of theitem 16 upon the receipt of a command signal, the likelihood of reception of the command signal is reduced by the presence of theinner layer 20. The ballistics materialouter layer 22 provides protection in the event that theitem 16 detonates, reducing or restricting the distance through which fragments thereof are projected in such an event. - In accordance with the invention, located within the
volume 18 are afirst antenna 24 and ahousing 26 containing a second antenna. The second antenna conveniently takes the form of a discrete conductor located within thehousing 26, but it will be appreciated that it could take other forms. Thefirst antenna 24 takes substantially the form of a loop suspended from the covering 12 bysupport 28. Thesupport 28 may take the form of a ring of a flexible material, for example a suitable textile material. Thesupport 28 carries the first antenna at a location spaced inwardly of the electromagnetic screeninginner layer 20 by a small distance. In the arrangement shown, thefirst antenna 24 is located at a position spaced from the apex of the covering 12 by approximately one third of the height of the covering 12. It will be appreciated that this represents just one example, and that the invention is not restricted in this regard. The position of thefirst antenna 24 is selected in such a manner as to ensure that an inhibiting signal transmitted therefrom, in use, can be reliably received throughout substantially the entirety of thevolume 18. By spacing thefirst antenna 24 from the covering 12, it will be appreciated that the risk of parts of the covering 12 impeding the transmission of a signal from theantenna 24 to parts of thevolume 18 is reduced. Also, signal transmission power may be reduced without negatively impacting upon received signal strength within parts of thevolume 18. - The
housing 26 containing the second antenna is supported uponstraps 30 adjustably secured to thecovering 12, the manner in which thestraps 30 are secured to the covering 12 being such as to allow the effective lengths thereof, and hence the height at which thehousing 26 is supported within thevolume 18, to be adjusted. By way of example, thestraps 28 may include hook and look material fasteners, allowing them to be adjustably secured to the covering. - By arranging for the position of the
housing 26 to be adjustable, in use, it can be supported very close to theitem 16, thereby maximising the inhibiting effect of an inhibiting signal transmitted therefrom. - The
housing 26 may further contain one or more additional similar antennae. - The
first antenna 24 and the second antenna (and any further antennae) are connected by means of amulti-core cable 30 to an inhibitor device 32 operable to generate respective inhibitor signals for transmission by the antennae. By way of example, the inhibitor device 32 may include a plurality of variable signal sources such as programmable voltage controlled oscillators arranged to generate the respective inhibitor signals. - In use, upon identifying that a
suspicious item 16 is present, the covering 12 is positioned over the item, thecable 30 is connected to the inhibitor device 32 and the inhibitor device 32 is used to transmit, via the first and second antennae, at least, inhibiting signals into thevolume 18. Before positioning the covering 12, thestraps 28 may be adjusted so as to ensure that thehousing 26 is supported as a suitable level close to theitem 16. As described hereinbefore, the presence of the covering 12 attenuates external signals transmitted to theitem 16, and provides physical protection in the event of detonation. The inhibiting signals serve to further reduce the likelihood of reception of a command signal by the item, and so reduce the likelihood of remotely controlled detonation. The inhibiting signals are contained, primarily, within thevolume 18 by the covering 12, and so the continued operation of communications equipment in the vicinity of theprotection device 10 is not particularly impeded. - It will be appreciated that by providing a plurality of antennae, the protection device is able to transmit inhibiting signals at or over a wider range of frequencies than is possible using a single antenna. As a result the device may be used to inhibit the reception of command signals transmitted over, for example 3G and 4G cellular networks, as well as by, for example, VHF and other wireless communications bands. By appropriate location of the antennae within the
volume 18, the transmission of the inhibiting signals at an unnecessarily high signal strength is avoided, aiding containment thereof. - Whilst a specific embodiment of the invention is described hereinbefore, it will be appreciated that a wide range of modifications and alterations may be made without departing from the scope of the invention as defined by the appended claims.
